from the world's big
In the net game, I met my best brother named David. He is a friendly boy and often takes care of me kindly all the time. In this game, when he has a lot of FFXI Gil, he will give me half of them. At the beginning, I do not understand why he does that for me, but gradually, I know that his family is very rich, but he fells very lonely in his spare time because his parents do business and do not have time to communicate with him. Although they give him plenty of money, I know that he does not need money at all. In fact, he only wants to have a person that can chat with him and listen to his words about his living. On an occasional chance, he finds a net game to play with the strange, and then we meet in the unreal world. In my memory, when we met for the first time in the net game, my all FFXI gold had been bam and I had no money to buy blood. At that time, walking across a forest, a big bear came over and was beating me again and again. I faced the danger and need the help to go through it. Who could help me? I said to myself. Just on that time, David saved me from the danger and he added a lot of blood to me to kill the bear, and in the following, I was out of the danger finally. He asked me why I did not add the blood when I stayed here. I told him my difficulty and then he gave me a lot of money and said that I could use the money to buy cheap Final Fantasy XI Gold. Besides, he told me where to buy the blood. On hearing his words, I was moved to cry out and told him that I would return her money in the near future but he only smiled at me and then went away without words. In order to make my promise come true, I will spend most of time to surf in the game. However, I have never met him for a long time and begin to worry about him. Maybe, the god has listened to my wish and I met him again today. We exchanged our best regards and I inquire him whether we can become the best friends in the game. He gives me his agreement and in the following days, he often tries his best to buy FFXI Gil for us and tells me that he would not charge me for the Final Fantasy XI gold because I am a student having no more money. I hope that our friendship will last for ever.
What would it be like to experience the 4th dimension?
Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.
If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.
- Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
- Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
- One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.
Duke University researchers might have solved a half-century old problem.
- Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.
Duke researchers have developed the first gel-based synthetic cartilage with the strength of the real thing. A quarter-sized disc of the material can withstand the weight of a 100-pound kettlebell without tearing or losing its shape.

Their <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/adfm.202003451" target="_blank">new paper</a>, published in the journal,<em> Advanced Functional Materials</em>, details this exciting evolution of this frustrating joint.<br></p><p>Researchers have sought materials strong and versatile enough to repair a knee since at least the seventies. This new hydrogel, comprised of three polymers, might be it. When two of the polymers are stretched, a third keeps the entire structure intact. When pulled 100,000 times, the cartilage held up as well as materials used in bone implants. The team also rubbed the hydrogel against natural cartilage a million times and found it to be as wear-resistant as the real thing. </p><p>The hydrogel has the appearance of Jell-O and is comprised of 60 percent water. Co-author, Feichen Yang, <a href="https://today.duke.edu/2020/06/lab-first-cartilage-mimicking-gel-strong-enough-knees" target="_blank">says</a> this network of polymers is particularly durable: "Only this combination of all three components is both flexible and stiff and therefore strong." </p><p> As with any new material, a lot of testing must be conducted. They don't foresee this hydrogel being implanted into human bodies for at least three years. The next step is to test it out in sheep. </p><p>Still, this is an exciting step forward in the rehabilitation of one of our trickiest joints. Given the potential reward, the wait is worth it. </p><p><span></span>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.
